In South Texas, particularly in San Antonio, summer heatwaves are not just intense—they’re relentless. With temperatures often soaring above 100°F, ensuring your air conditioning system is in top shape is crucial. Proper air conditioning maintenance can make the difference between a comfortable home and an unexpected breakdown.
What is a Heat Wave in Central Texas?
In Central Texas, a heat wave is defined as a stretch of extremely hot days—typically two or more—when temperatures soar well above our area’s usual averages. And let’s face it: what might feel scorching elsewhere often feels like just another summer day around here. But even by Texas standards, true heat waves push temperatures—and our AC systems—to the limit.
What Causes Central Texas Heat Waves?
Heat waves are usually caused by a high-pressure system that traps hot air in place, creating a dome of heat over the region. With climate change, we’re seeing more frequent and intense heat waves across Texas.
Take the summers of 2023 and 2024, for instance. These were the hottest summers on record in Texas and the hottest years globally. That kind of sustained heat can be dangerous—especially if your HVAC system isn’t ready for it.
Stay Safe and Stay Cool
The best way to deal with Central Texas heat is to stay informed, stay hydrated, and make sure your HVAC system is prepped and running efficiently. A well-maintained system can make all the difference when the next summer heatwave hits.
Why AC Maintenance Matters in San Antonio
The unique climate of San Antonio and the Hill Country—with its high humidity and scorching temperatures—places extra strain on HVAC systems. Regular AC maintenance ensures your system runs efficiently, reduces energy bills, and extends the lifespan of your unit. Neglecting maintenance can lead to costly AC repair services down the line.
Tip #1: Regularly Replace or Clean Air Filters
Dust and pollen levels are high in Central and South Texas. Clogged filters restrict airflow, forcing your system to work harder. Check filters monthly and replace or clean them as needed to maintain optimal performance.
Tip #2: Maintain Your Outdoor Condenser Unit
Before the summer heatwaves roll in, schedule a professional AC inspection and tune-up—ideally in the spring. Regular maintenance is key to making sure your central AC or heat pump stays efficient during the extreme Central Texas heat.
During the tune-up, your HVAC technician will likely clean the condenser coils, inspect the fan, capacitor, refrigerant lines, and blower, and ensure refrigerant levels are correct—recharging if needed.
You can help too. Make sure to clear away leaves, grass, or debris from around the outdoor condenser unit and trim back any nearby plants. Good airflow around the unit keeps it from working harder than it has to—and that means better cooling and lower energy bills.
Tip#3: Check Thermostat Settings
Optimize your thermostat settings for energy efficiency. Consider upgrading to a programmable thermostat to better control indoor temperatures and reduce energy consumption.
Tip #4: Address Repairs Promptly
Unusual noises, reduced cooling efficiency, and higher energy bills can mean it’s time for an AC repair. Delaying repairs can lead to more significant issues. Shafer Services Plus offers reliable AC repair services in San Antonio and the Hill Country to keep your system running smoothly.
Stay Cool and Comfortable
Everyone wants their home to be a refuge, and that’s difficult in the brutal Texas heat. Staying on top of air conditioning maintenance can help!
Regular maintenance not only enhances comfort but also saves money by preventing costly repairs and improving energy efficiency.
